Publication number: 20170135112Abstract: A wireless communications system including a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device.Type: ApplicationFiled: January 25, 2017Publication date: May 11, 2017Applicant: SCA IPLA HOLDINGS INC.Inventors: Timothy James Speight, Paul William Piggin

Publication number: 20170127395Abstract: A method for communicating data between a base station and a terminal device in a wireless telecommunications system, for example an LTE-based system. The wireless communication system uses plural frequency sub-carriers spanning a system frequency band. Physical-layer control information for the terminal device is transmitted from the base station using sub-carriers selected from across the system frequency band, for example to provide frequency diversity. However, higher-layer data for the terminal device is transmitted using only sub-carriers selected from within a restricted frequency band which is smaller than and within the system frequency band. The terminal device is aware of the restricted frequency band, and as such need only buffer and process data within this restricted frequency band during periods where higher-layer data is being transmitted. The terminal device buffers and processes the full system frequency band during periods when physical-layer control information is transmitted.Type: ApplicationFiled: January 18, 2017Publication date: May 4, 2017Applicant: SCA IPLA HOLDINGS INC.Inventor: Martin Beale

Patent number: 9622166Abstract: A wireless communications system includes a base station, a plurality of intermediate devices and a terminal device. The base station is operable to wirelessly transmit downlink signals to the terminal device, the downlink signals including terminal control signals identifying one of the intermediate devices as a target device to which the terminal device is to direct uplink signals intended for the base station. The terminal device wirelessly transmits the uplink signals to the base station via the intermediate device identified by the terminal control signals. In this way, downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define the uplink route from the terminal device to the base station via one or more intermediate devices.Type: GrantFiled: June 13, 2012Date of Patent: April 11, 2017Assignee: SCA IPLA HOLDINGS INCInventor: Yuichi Morioka

Downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define an uplink route from the terminal device to the base station via one or more intermediate devices. Power is conserved at the terminal device on the uplink because a lower power transmission can be used which although insufficient to reach the base station can reach the intermediate device. The terminal device is not required to determine the uplink path itself and therefore does not require complex, expensive, and power consuming control logic.Type: ApplicationFiled: November 4, 2016Publication date: February 23, 2017Applicant: SCA IPLA HOLDINGS INCInventor: Yuichi MORIOKA
